Dorian's Duelist Weapon

You create a magical weapon in your hands that lasts for the duration or until you cast this spell again. You can create any weapon of your choice and decide how it looks, you become proficient in it and it is magical for the purpose of overcoming resistance.

The weapon uses its normal ability score for attacks and damage rolls and deals its normal weapon die plus an additional 1d10 radiant damage on a hit. You can create multiple weapons at a time provided you have the necessary components to do so and before making an attack with the weapon you can change its form to another weapon of your choice, changing its statistics accordingly. 

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for every level.
